Electrically controlled rotary holding device

摘要

The present invention provides a rotary holding device for an electrically actuated brake system in a vehicle including a rotor assembly including a plurality of teeth and a stator assembly including a plurality of teeth. The stator assembly teeth are positioned adjacent the rotor assembly teeth and a coil is positioned to allow a magnetic flux to align the rotor assembly teeth and the stator assembly teeth when the coil is energized to hold a motor shaft coupled to the device.
